Description
Accurate modelling of the solar atmosphere is essential for understanding the energy flow and build-up that underpins the heating of the solar chromosphere and corona, and drives eruptions and flares. Such a model would need to be able to capture the fundamental physical, radiative and ionisation states of the vastly different atmospheric layers of the Sun and the complex coupling between them. However, no model exists with the capability to accurately capture all the key processes of the different parts of the atmosphere, but one is necessary to understand the cutting-edge observations produced by new facilities and provide the much-needed step-change in our understanding of how the solar atmosphere works. In this talk I will present our proposal to develop a software framework (the Solar Atmospheric Modelling Suite - SAMS). We have been funded to build a modular code containing an exascale-ready, GPU-accelerated MHD engine coupled with a wide range of physics modules including 3D radiative transfer, updated atomic models and multi-fluid capabilities. SAMS will also include an integrated pipeline to take the simulation output to provide synthetic observables. I will provide an overview of what will be our first steps and our future plans and how we aim to engage the whole community in the project.
